基于FPGA的图像实时处理系统的设计

Design of Image Acquisition and Processing System Based on FPGA

摘要:

设计了基于FPGA的图像实时处理系统, 利用FPGA中IP核的内置缓存模块, 通过乒乓结构读写, 实现了图像数据在FPGA内部的缓存和提取。同时利用FPGA数据并行处理的特点, 实现了图像的二值化和边缘提取等预处理, 将图像预处理的时间由原来在DSP内的1s缩小到50ms以内, 使实时图像处理成为可能。

Abstract:

The proposed design uses IP core of memory controllers and Ping-pong structure to realize the real-time image data storage and extraction. The design also realizes the image pre-processing such as binarization and edge extraction through data parallel processing in FPGA. System simulation and test results show that the image pre-processing time can be shorten from 1s in DSP to less than 50ms.
